57 - 4t > = 13.....subtract 57 from both sides -4t > = 13 - 57 -4t > = - 44 ...divide both sides by -4, and change the inequality sign t < = -44 / -4 t < = 11
u solve inequalities much like u do equations except for one very important rule. In an inequality, if u divide/multiply by a negative number, u have to change the inequality sign.
Work: 57-4t>/13 Solve for t -57 both sides -4t>/-44 ÷-4 both sides Flip sign since you are dividing by a negative T < / 11 Answer: t < / 11 Check your work: 10 is less than 11 plug in 10 57-4 (10)>/13 57-40>/13 17>/13 The answer is correct
